                                   STIPULATION
                                   -----------

         The  signatories  to this  Stipulation,  as indicated on the  signature
page, are collectively  referred to herein as the "signatories." The signatories
have  jointly  prepared  and submit this  Stipulation  to the New Mexico  Public
Regulation Commission ("Commission" or "PRC") for approval in this case:

                                   BACKGROUND
                                   ----------

         1. In its Final Order in NMPUC Case No.  2752  issued on  February  13,
1997, the New Mexico Public Utility  Commission  ("PUC")  ordered Public Service
Company of New Mexico ("PNM") to file an electric general rate case using a test
period of the 12 months ending December 31, 1996.

         2. In accordance with  subsequent PUC orders,  on November 3, 1997, PNM
filed  its  Advice   Notice  No.  258  and  its  petition  for  all   approvals,
authorizations and variances  necessary for PNM to implement 13 proposed revised
rates and 14 proposed  new rates and to cancel 3 current  rates.  PNM also filed
its Experimental Incremental Interruptible Power Rate ("EIIPR") Final Report.



         3.  Subsequently,  the  Commission  suspended  PNM's proposed rates and
appointed Peter E. Springer as Hearing Examiner to preside over hearings in this
case.
         4. After an evidentiary hearing and submission of post-hearing  briefs,
the PUC issued its Final  Order on  November  30,  1998,  from which PNM took an
appeal to the New Mexico Supreme Court in Docket No. 25,513.  On March 15, 1999,
the Court issued its Decision, vacating and annulling the PUC's Final Order and,
thereafter, the Court remanded Case No. 2761 to the PRC "for further proceedings
consistent  and in  conformity  with the  decision  of this  Court  and with the
opinion issued in Cause No. 25,523, State ex rel. Sandel v. PUC."

         5. The PRC entered its Order Establishing Procedures on Remand on April
20, 1999,  finding  that this matter  should be brought to final  resolution  as
expeditiously  as  possible  and that the  signatories  should  be  allowed  the
opportunity  to  reach a  negotiated  settlement  in  order  to  expedite  final
resolution.

         6. By entering into this  Stipulation the  signatories  intend to serve
the public interest by bringing this case to final  resolution as  expeditiously
as possible,  providing immediate  implementation of lower rates and tariffs for
all PNM  customer  classes,  rate  stability  for PNM's  customers  and  revenue
stability for PNM.

         NOW THEREFORE,  in  consideration  of their mutual  promises and of the
benefits they and their respective constituencies will receive, the signatories,
through their  undersigned  authorized  representatives,  stipulate and agree as
follows:

                                       2



                                 RATE REDUCTION
                                 --------------

         7. PNM  shall  file new  tariffs  which  shall  reduce  its New  Mexico
jurisdictional  1996 test period  annualized  revenues of $504,903,847  filed in
Case No. 2761 by $34,000,000, based on 1996 billing determinants.  These tariffs
shall be effective for all bills rendered on and after July 30, 1999. If a final
order approving this  Stipulation is entered after June 30, 1999 and as a result
PNM is unable to implement the rate reduction agreed to herein by July 30, 1999,
the rate reduction will  nevertheless be effective for all bills rendered on and
after July 30, 1999.  PNM will  implement the rate reduction with the first full
monthly  billing  cycle  which  begins  30 days  after  entry  of a final  order
approving  this  Stipulation  and shall refund or credit to customers any excess
revenues  collected  as a result  of the delay in  implementation  past July 30,
1999.

         8. To comply with ss. 18 of the Electric Utility Industry Restructuring
Act of 1999, Laws of 1999, ch. 294 ("the Act"), PNM shall also file a second set
of new tariffs  which shall  reduce New Mexico  jurisdictional  1996 test period
annualized revenues by an additional $7,409,457 to reflect that local government
franchise fees ("franchise  fees") currently  charged by government  authorities
shall be  collected  from and  stated  as a  separate  line item on the bills of
customers located within the jurisdiction of the government  authority  imposing
the fee.  This second set of tariffs will replace the tariffs  described in P. 7
once  PNM's  customer  billing  system  (Banner)  has been  modified  to reflect
franchise  fees as a separate line item on customers'  bills.  PNM will use best
efforts  in good  faith to  implement  this  second  set of  tariffs  as soon as
possible,  with franchise fees as a separate line item charged only to customers
located within the  jurisdiction of the government  authority  imposing the fee.
But in any event,  PNM will  comply with all  Commission  orders  applicable  to
franchise fees.  Notwithstanding the foregoing language, the signatories to this
Stipulation  expressly  reserve  all  rights  and  remedies  they may have under
Section 18A of the Act.


                                       3


         9. The annual base rate revenue  reductions  set forth in  paragraphs 7
and 8 will be allocated  among  current rate classes pro rata on a revenue basis
as shown in  Attachments A and B,  respectively  to this  Stipulation.  Specific
tariffs reflected in Attachments C and D, respectively, to this Stipulation show
how the resulting $470,903,847 or $463,494,390 of revenues will be collected.

         10. The  Experimental  Incremental  Interruptible  Power Rate ("EIIPR")
will be continued on a  non-experimental  basis for customers on that rate as of
the  date of the  execution  of this  Stipulation,  will not be  offered  to new
customers, and will be called the Incremental Interruptible Power Rate ("IIPR").
The rates on the IIPR and on the  economic  development  rate riders will not be
reduced.

         11. The signatories agree that Tariff 16, PNM's Special Changes tariff,
should  be  approved  as part of this  Stipulation.  Tariff  16 is  included  in
Attachments C and D to the Stipulation.

                                 RATE STABILITY
                                 --------------

         12.  Except  as  otherwise  provided  in this  Stipulation,  the  rates
stipulated  to herein and PNM's  Street and Private  Area  Lighting  rates shall
continue in effect,  regardless  of any changed  circumstances,  until  customer
choice service is implemented in accordance  with ss. 4 of the Act or January 1,
2003, whichever occurs first.

         13. Under Section  4(A)(1) of the Act customer  choice service is to be
implemented  for  public  post-secondary  educational  institutions  and  public
schools,  residential and small business  customers  before all other customers.
Therefore, the rates for each customer class stipulated to herein will remain in
effect until customer  choice service is implemented  for that class even though
customer choice service may have been previously implemented for another class.


                                       4

         14. The signatories will not institute on their own motion or encourage
or support another person to seek or initiate any proceeding requesting a change
in PNM's  rates  which would take  effect  prior to  implementation  of customer
choice service under the Act. If at any time after approval of this  Stipulation
any person petitions or otherwise seeks from the Commission a rate case or other
proceeding or the Commission initiates a rate case or other proceeding to review
the  reasonableness of PNM's revenue  requirements and to seek a change in rates
that would become effective prior to  implementation  of customer choice service
under the Act, the  signatories  will state their support for the  provisions of
this  Stipulation  and the  continuation  of the rates  stipulated  herein.  The
signatories  will  support,  and  work in good  faith  and to the  best of their
abilities to meet,  the  timeframes  established  in Section 4(A) of the Act for
implementation  of customer choice service and will not institute or support any
delay in these  timeframes  unless  necessary to maintain  adequate and reliable
service to customers.  This does not preclude the  signatories  from  requesting
extensions  of time,  continuances  or other  appropriate  relief  from  hearing
schedules or other deadlines in PRC proceedings initiated pursuant to the Act.

         15.  Except as  otherwise  provided  in this  Stipulation,  before  the
effective date of customer  choice  service,  the  signatories may make filings,
subject  to  Commission  approval,  that  modify  tariffs,  riders and terms and
conditions of rate  schedules or which propose new tariffs,  riders or terms and
conditions,  so long as such  changes or  additions  do not increase or decrease
base  rates  reflected  in the  rate  schedules  implemented  pursuant  to  this
Stipulation  or  increase  or  decrease  revenues  to PNM based on 1996  billing
determinants.  However,  this Stipulation  shall not preclude PNM from proposing
decreases in rates or revenues.


                                       5


         16.  Notwithstanding  any provision herein to the contrary,  before the
effective date of customer  choice  service,  the  signatories may make filings,
subject to Commission approval,  that modify or propose new tariffs,  riders and
terms and conditions of rate schedules if any governmental authority imposes (a)
a new franchise fee or a change in an existing franchise fee or (b) the Case No.
2787 renewable energy surcharge.  In addition,  PNM may seek approval of tariffs
to recover from governmental authorities increased costs of a siting, permitting
or construction  requirement that mandates the  extraordinary  undergrounding of
distribution  facilities not recovered under PNM's line extension  policy or the
undergrounding  of  transmission  facilities;  provided  however,  a requirement
mandating  undergrounding  necessary  to comply  with  state or  federal  rules,
regulations  or laws shall not be included in such request to recover  increased
costs from governmental  authorities.  The signatories will not oppose a request
by PNM for a Commission  hearing or rulemaking on the recovery from governmental
authorities  of  increased  costs  of  the   extraordinary   undergrounding   of
distribution  facilities not recovered under PNM's line extension  policy or the
undergrounding of transmission facilities required by such authorities.

         17.  Nothing  herein  shall  affect the  operation of NMPUC Rule 330 or
PNM's Tax Adjustment Clause or PNM's Palo Verde  Refinancing  Credit approved in
Case No. 2837 which is stated as a separate line item on customers' bills.

         18. The  signatories  acknowledge  that this  agreement to reduce rates
constitutes  valuable  consideration  which the signatories  have given based on
their  expectation  that base rates will not be changed  until  customer  choice
service  is  implemented  or  January  1,  2003,  whichever  occurs  first.  The
signatories  further  acknowledge that they have agreed to the rate reduction in
reliance on and in exchange  for the other  signatories'  promise that they will
not support  docketing  any  proceeding  to review the  reasonableness  of PNM's
rates,  to seek a change in rates prior to  implementation  of  customer  choice
service,  or support a delay in the  implementation  of customer  choice service
beyond  the dates  set forth in  Section  4(A) of the Act,  except as  otherwise
provided in this Stipulation.

                                       6


                               GENERAL PROVISIONS
                               ------------------

         19. The signatories  will use their best efforts to obtain  expeditious
implementation  of  this  Stipulation  by  the  entry  of an  appropriate  final
Commission  order. This Stipulation  assumes the legality and  enforceability of
the  rates and  agreements  set forth in this  Stipulation.  Should  any rate or
agreement  set forth in this  Stipulation  be rejected,  modified or directly or
indirectly rendered inoperable by Commission or Court decision,  any party shall
have the  right,  by  filing a notice of  withdrawal  with the PRC  within  five
working days, to withdraw from this  Stipulation and render this  Stipulation of
no further force and effect, in which case the signatories shall attempt in good
faith to negotiate an appropriate substitute rate or agreement.

         20. Under  Commission Rule 531 adopted by the PUC in Case No. 2816, PNM
is  required,  for  informational  purposes,  to  functionalize  the rates which
implement the revenue  reduction  agreed to herein.  The signatories  agree that
neither the  methodology  used to  functionalize  PNM's rates nor the  resulting
functionalized  rates after the rate  reduction to comply with  Commission  Rule
531, shall in any way bind the signatories,  constitute an admission or have any
precedential effect in any proceeding, including,  specifically, any proceedings
and determinations required under the Act.


                                       7


         21. The rate design,  rate design  method,  the  allocation  of revenue
requirements and the allocation method for setting revenue  requirements  agreed
to in this  Stipulation  reflect  various  compromises  of the  positions of the
signatories in this case for  settlement  purposes only and shall not constitute
an  admission  of any kind or otherwise  bind any  signatory  or  establish  any
precedent or  presumption  in any other  proceeding,  including any  proceedings
required by the Act.

         22. This Stipulation shall not prejudice, bind, or affect any party, or
be viewed as an admission,  except to the extent  necessary to give effect to or
enforce the terms of this  Stipulation or unless otherwise  specifically  stated
herein. In the event this Stipulation is not approved by the Commission, nothing
in this  Stipulation  or  negotiations  leading  up to its  execution  shall  be
construed as an admission of a signatory's  position on any issue nor be used or
offered into evidence by any signatory in this or any other proceeding.

         23. Neither this  Stipulation  nor changes or deletions in the proposed
4000B tariff to the section entitled,  "Service With A Contract Demand of 10,000
KW Or More:" shall  prejudice,  bind,  or serve as an admission by any signatory
regarding  the historic  application/availability  of PNM's  current  tariffs to
specific     customers    or    regarding     the    provision    of    electric
generation/transmission  to the United States Executive  Agencies  facilities by
the Western Area Power Administration.

         24. In its  transition  plan filed  pursuant to the Act,  PNM agrees to
propose methods to address the situation of customers  which,  after open access
pursuant to the Act, may not have genuine access to markets and suppliers beyond
PNM's  system,  and as such  could be  exposed to  excessive  market  power of a
competitive power supplier.


                                       8

         25.  This  Stipulation  shall  remain in  effect  until  terminated  or
modified by unanimous consent of the signatories,  except as otherwise  provided
in this Stipulation.

         26. This  Stipulation  expresses  the full  intent,  understanding  and
entire agreement of the signatories concerning the subject matter hereof.

         27. This Stipulation  shall be binding upon and inure to the benefit of
the heirs, successors and assigns of the signatories.

         28. Approval of this Stipulation shall be entered as the Final Order in
Case No. 2761.

         29.  Other  signatories  may  agree to the  terms  of this  Stipulation
         through the execution of a separate  signature  page.  Duly  authorized
         representatives  of  the  signatories  have  signed  or  telephonically
         approved this Stipulation as of the 21st day of May, 1999.
